NH4(NH2CO2)(s) ⇌ 2NH3(g) + CO2(g) Kp = 0.0596

NH4(NH2CO2)(s) ⇌ 2NH3(g) + CO2(g) Kp = 0.0596

 

 

For the decomposition of ammonium carbamate

NH4(NH2CO2)(s) ⇌ 2NH3(g) + CO2(g)

Kp = 0.0596 at a certain temperature.

A solid sample of ammonium carbamate is introduced

into an evacuated container and

at equilibrium some solid remains in the container.

What is the total pressure in the container?

평형에서 .................... 2x ............ x

( 참고 https://ywpop.tistory.com/3760 )

 

 

 

Kp = (2x)^2 (x) = 4x^3 = 0.0596

 

x = (0.0596 / 4)^(1/3)

= 0.246 atm

 

 

 

평형에서,

(2x) + (x) = 3x 이므로,

3 × 0.246 = 0.738 atm

 

 

 

답: 0.738 atm
